侧鞍骑乘（英语：riding Side-saddle ）是一种特殊的骑乘方式，通常为女性骑手所采用。这种骑乘方式容许骑手把双腿侧放在鞍具的一侧（通常是左侧），而不是像常规骑乘那样跨坐在驮兽（如马、毛驴、骡子等）的背上，双腿分别放置于鞍具的两侧。侧鞍骑乘的历史可以追溯到中世纪时期的欧洲，当时欧洲妇女（特别是那些出身贵族阶层的）为了在身穿长裙的情况下仍然可以保持庄重的仪态，特意采用了这一特殊的骑乘姿势。时至今天，在许多西方国家仍然经常可以看到身穿长裙的妇女，在出席重要场合或仪式时，采用这种骑乘方式。

Sidesaddle riding is a form of equestrianism that uses a type of saddle which allows a rider (usually female) to sit aside rather than astride an equine. Sitting aside dates back to antiquity and developed in European countries in the Middle Ages as a way for women in skirts to ride a horse in a modest fashion while also wearing fine clothing. It has retained a specialty equestrian niche even in the modern world.
